NIST experiment reveals new measurement for universal gravitational constant
Physicists at the National Institute of Standards and Technology opened a sealed envelope after ten years to reveal a new measurement of the universal gravitational constant.
Decade-long study yields unexpected result
Stephan Schlamminger led the team that spent ten years measuring big G. The final data produced a value that differs from another leading result in the field. This discrepancy deepens a physics puzzle that has existed for 225 years.
Scientists question source of error
Researchers are unsure if hidden experimental errors caused the difference or if something more surprising is involved. The gap between measurements is tiny but significant enough to challenge current understanding. NIST notes that this finding keeps scientists wondering about the nature of gravity.
